CONILWIQIDING DEVICE.

Application filed N bvember 23, 1925. Serial No. 70,931. 'fi L""-'."I w l f Ii-"K This invention relates to improvements ,in the art of winding arn or thread andhas especial reference to yarns used for knitting machines wherein the y'ai'nis wound 'in the 5 form of a truncatedcon c. i I

"An object of the present invention is to provide means for orming depressions or recesses within the length of the wound cone, so that should breakage of the yarn occur during the winding} operation, the knotted portion of the yarn may be placed and kept in these depressions and thus be out of the path of the yarn as the latter is unwound, so that the said yarn will not be caught over the knot and increase the tension on the yarn with aresultant damage to a finished article.

It is therefore the purpose of the invention to provide for a uniform tension of the yarn as the latter is unwound from the cone. With the above and other objects in view,

the invention further includes the following novel features and details of construction,

to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings:

Figure 1 is a fragmentary top plan view illustrating the use of the invention.

Figure 2 is a side elevation of the subject matter illustrated in Figure 1 with a portion in section.

Figure 3 is a fragmentary elevation illustrating a slightly different form of the invention.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a portion of an ordinary yarn or thread winding machine, 11 a portion of a rotatably mounted shaft and 12 a tapered or cone-shaped core or mandrel upon which the yarn is wound, the yarn taking on the shape of a truncated cone as illustrated at 13.

Frequently, during the winding operation the yam is broken and it is necessary to connect the broken ends by means of a knot so as to continue the winding operation. As a result of this, when the yarn is unwound by a knitting or other machine, the

knot will be in the path of the unwinding yarn so that the latter will engage and catch upon the knot. This will increase the tension on the yarn so that the latter is frequently broken, or a stitch dropped by the knitting machine, with the result 'Ofail iniperfect place the knitted article. l l

The presentinventionovercomes this dis.- advantage by providingv depressions which are formed during thewinding operation to receive the knotted portion o fthe yarn and to hold the knot or knots in these depressions, so that when the yarn is unwound the knot will be out of the way andthe yarn will be unwound in a uniform manner and at a uniform tension.

For this purpose there is provided a shaft 14 upon which is pivotally mounted spaced arms 15. These arms are each shown in Figures 1 and 2 of the drawings as being formed of spaced parallel members which carry at their outer ends rollers 16, while their inner ends are mounted upon the shaft 14- and are held in proper spaced relation by collars 17. The shaft 14 is stationary and rigid with this shaft are arms 17, one of which is provided for each of the arms 15. The arms 18 and 15 are connected by springs 19 which act to force the rollers 16 in yield in engagement with the yarn of the cone 13.

In Figure 1 of the drawings, the arms 15 and their rollers are so spaced as to provide depressions 20 at opposite ends of the cone 13 and when a breakage occurs in the yarn, the knot which is shown at K is placed in the depression nearest the point of breakage and is held therein by the particular roller 16 forming this depression so that it will remain ,in the said depression during the remainder of the winding operation.

In some types of yarns, for example, mercerized yarns which are of a slippery character, the knotted portions will not remain in the depressions at the ends of the cones and to provide for this relatively close depressions are formed in the cone 13 as indicated at 21 in Figure 3 of the drawings. These depressions are formed by spaced rollers 16' which are mounted within spaced parallel arms 15', the rollers 16 being located between the outer ends of these arms and held in proper spaced relation by a sleeve 22. The arms 15 are mounted for pivotal movement after the manner of the arms 15.

In the form of the invention shown in Figure 3, the knot K is placed in the lowermost depression 21 and when the said knot slips forward itfalls into the upper depression where it, remains and ix thus out of the way of the ja1'n when the latter is unwound. Due to the slippery eharaeter ot mereerized 'arn the knot would slip otl of the top or bottom of the cone it the knot were plan-ed in depressions similar to those illti: ii':ited in Figures 1 and 2 of the drawings.

The invention is suseeptihle ot' variona changes in its form. proportiom and minor details of eonstruetion and the rie'ht ix herein reserved to make sueh ('l1;l'i1; "(?r as properly fall within the scope of the appended elainu Having described the invention what is claimed is 1. The combination with a. yarn vi' inding machine of means acting upon the yarn as the latter is hein wound to provide annular depressions in the wound yarn.

'12. The eomhination with a yarn winding maehine, ot pivotallt mounted meane aetin upon the yarn as the latter is being wound to provide annular depreesions in the wound yarn and means to yieldingly hold the pivot- :zlly mounted n1 2111? in active position.

23. The eonihination with a *arn winding maehine, of spaced pivotally mounted anus rolleiw at the outer ends of the arm to en gag-e the yarn 21 the latter is heine' wound and means to yieldinglv three the roll rs into sneh engagement to provide .-paeed annular depreseions in the wound yarn.
